In Kenntnis dieses Standes der Technik hat sich der Erfinder das Ziel gesetzt, die erkannten Mängel an Vorrichtungen der eingangs erwähnten Art zu beseitigen, deren Funktionsweise, Handhabung und Einsatzmöglichkeiten zu verbessern sowie das Einführen in die Hohlprofile erheblich zu vereinfachen.In Knowing this state of the art, the inventor has the goal set, the detected shortcomings to eliminate devices of the type mentioned, whose Functionality, handling and application possibilities improve as well the introduction to simplify considerably in the hollow sections.
Zur Lösung dieser Aufgabe führt die Lehre des unabhängigen Anspruches; die Unteransprüche geben günstige Weiterbildungen an.to solution performs this task the teaching of the independent claim; to give the dependent claims favorable Further education.
Erfindungsgemäß sind zwei aus Kunststoff geformten zylindrischen Rohren zwei konzentrische Ringteile unterschiedlicher Höhen als Halteelemente zugeordnet und der innenliegende Ringteil geringerer Höhe ist der einen Endkante des anderen Ringteils zugeordnet; zwei der etwa radialen Wandstege sind einander benachbart und flankieren einen durchgehenden achsparallelen Radialspalt der Einsatzeinrichtung. Infolge dieses besonderen Merkmals, in der insgesamt ringförmigen Einsatzeinrichtung einen von zwei benachbarten Wandstegen begrenzten -- vorteilhafter Weise achsparallelen -- Radialspalt vorzusehen, wird die Einsatzeinrichtung zu einer Art Federring.According to the invention are two plastic molded cylindrical tubes two concentric ring parts different heights assigned as holding elements and the inner ring part lesser Height is associated with one end edge of the other ring part; two of the approximately radial wall webs are adjacent to each other and flank a continuous axis-parallel radial gap of the insert. As a result of this special feature, in the overall annular insert a limited by two adjacent wall webs - advantageously axis-parallel - to provide radial gap, the insert device to a kind of spring washer.
Nach einem weiteren Merkmal der Erfindung entspricht die Höhe des innenliegenden Ringteils etwa einem Fünftel der Höhe des anderen Ringteils, und die -- insbesondere zumindest drei -- Wandstege sollen in etwa gleichen Abstandswinkeln verlaufen. Die sich zwischen den benachbarten Endkanten der Ringteile erstreckende Unterkante des Wandsteges verläuft entweder etwa rechtwinkelig zur Längsachse der Ringteile oder ist in einem Winkel zur Innenfläche des äußeren Ringteils geneigt. Dieser Winkel soll dann zu einem Winkel gleichgerichtet sein, der sich erfindungsgemäß zwischen den Wänden der Ringteile einerseits sowie der geneigten Ober- oder Außenkante des Wandsteges andererseits ergibt.According to a further feature of the invention The height of the inner ring part corresponds approximately to one fifth of the height of the other ring part, and the - in particular at least three - wall webs should extend in approximately the same distance angles. The extending between the adjacent end edges of the ring parts lower edge of the wall web either extends approximately at right angles to the longitudinal axis of the ring members or is inclined at an angle to the inner surface of the outer ring member. This angle should then be rectified to an angle which results according to the invention between the walls of the ring parts on the one hand and the inclined top or outer edge of the wall web on the other hand.
Um für das äußere Hohlprofil am äußeren Ringteil einen Anschlag zu erhalten, soll die Außenfläche dieses äußeren Ringteils mit einer ringförmigen Kragleiste versehen sein; an dieser schlägt dann die Endkante der/des Hohlprofile/s beim Aufstecken an. Zudem können zur Erhöhung der Reibung zwischen Hohlprofil und Ringteil aus dessen Außenfläche mehrere parallele Ringrippen herausgeformt sein. Die Querschnittsbreite der Ringrippen ist vorteilhafterweise kürzer als die Querschnittsbreite jener Kragleiste; ein bevorzugtes Verhältnis dieser Breiten liegt etwa bei 1 : 10.Around for the outer hollow profile on the outer ring part to get a stop, should the outer surface of this outer ring part with an annular cantilever be provided; at this beats then the end edge of the / of the hollow profile / s when plugging. moreover can to increase the friction between the hollow profile and ring part from the outer surface of several be formed parallel annular ribs. The cross-sectional width the annular ribs is advantageously shorter than the cross-sectional width that cantilever a preferred ratio of these widths is at about 1:10.
Im Rahmen der Erfindung liegt auch, dass der innere Ringteil an seiner Innenfläche mit einem Ringwulst als Eingriffsorgan für das in ihn gesteckte sowie in ihm verlaufende innere Rohrprofil versehen ist. Letzteres enthält einen Kupplungsbereich in seiner Rohrwand zur Aufnahme eines Ringwulstes des inneren Ringteils.in the Under the invention is also that the inner ring part at his palm with a torus as engagement member for the inserted into it as well in him running inner tube profile is provided. The latter contains one Coupling area in its tube wall for receiving a torus of the inner ring part.
Der mit seinem Kupplungsbereich zusammenwirkende Ringwulst grenzt an einen geneigten Abschnitt der Innenfläche des inneren Ringteils; dieser Abschnitt liegt bevorzugt oberhalb des Ringwulstes, unterhalb dessen ein zylindrischer Abschnitt des inneren Ringteils vorgesehen wird.Of the with its coupling region cooperating annular bead adjacent an inclined portion of the inner surface of the inner ring member; this section is preferably above the annular bead, below whose provided a cylindrical portion of the inner ring member becomes.
Insgesamt ergibt sich eine verhältnismäßig kostengünstig herzustellende sowie einfach zu handhabende Einsatzeinrichtung zum sicheren Verbinden der konzentrisch angeordneten Rohrenden.All in all results in a relatively inexpensive to produce and easy-to-use insert means for securely connecting the concentrically arranged pipe ends.
